含七元碳环的多环芳烃的合成及其光电磁功能

Synthesis and opto-electronic-magnetic functions of polycyclic aromatic hydrocarbons containing seven-membered carbon rings

非苯型多环芳烃(polycyclic aromatic hydrocarbons,PAHs)具有不同于苯型多环芳烃的独特物理化学性质.其中,含七元碳环的非苯型多环芳烃在过去的十多年中引起了合成化学家的研究兴趣并且作为新的共轭单元被应用于有机光电材料的研究.本文主要总结和讨论了近五年来该领域取得的新进展,包括非苯型多环芳烃中构建七元碳环的新合成方法以及该类共轭分子在有机半导体、手性光学材料及磁性材料等领域中的应用,并对该领域的发展进行了展望.

Non-benzenoid polycyclic aromatic hydrocarbons(PAHs)have unique physicochemical properties that are different from benzenoid PAHs.Non-benzenoid PAHs containing seven-membered carbon rings have attracted much attention from synthetic chemists in the past decades and have been used as new building blocks in organic optoelectronic materials.In this review,we summarized and discussed the recent progress in this field,including the new synthetic methods for constructing seven-membered carbon rings in non-benzenoid PAHs reported in recent years,and the applications of these conjugated molecules in organic semiconductors,chiral optical materials and magnetic materials.
